m (g, 3; i Kx /WM @i 8, 8, and their cranks 11, 11,

plication of power at all positions of the cranks, either in lifting or lowering the plunger. rl`he effect ot this motion is that the plunger is raised and lowered at eX- actly the desired speed of movement and with a very even distribution and unvarying operation as to power.

At their other ends shafts 12 are provided with miter gears 13 which Igear into driving miter gears l-l, 14;, ot driving sha-tt 15, mounted in suitable pillow blocks 16. Shat't 15, which as shown in Fig. 2 is arranged continuously along for both tanks el, A, is provided with a driven gear 17 and by a train ot' gearing 18, 19, '20, 21, and the usual accompanying shatting, bearings, etc., power is transmitted from driving pinion 22 motor 23.

The construction or" the companion tank A, A, as shown, or of additional pairs of tanks, is the same as aboverdescribed` it being understood that shaft 15 may be ei:- tended to any7 practicable length.

ln operation7 the cranks and pitmen havbeen properly 'set and located, as indicated in Fig, 1, which shows the position at the middle ot the stroke, rotation of the shaft-.ing 12, 1Q and cranks 11 in opposite directions etl'iects operation of the pitmen in the manner above indicated and with a resulting alternating motion ot the plungers of the two tanks with the accompanying resulting advantages.

As will be obso'ved, the pair ot pitnien are similarly arranged as to each otlrer the plunger, as in the oit tank but are set around 180@ so that they will be swinging down when the other set oit pitmen and cranks is swinging up. rlnhis movement is indicated by the arrows b, Z), an c, Fig. v1. The result is that one ot the plungers balances the other and to large e3;- tent reduces the necessary power.

ln Figs.` l, 5, and t3, l show the same general arrangemento't the parts, as to the driving mechanism and their connection with the plungers by the pairs of' pitmen 3', with the several other attendant parts, similarly indicated by numerals havingthe eX- lponent a. ln such case, however, each tank equalization of the load in the sameway as in the case otheoppositely acting single plungers already described. The object ot integree such arrangement will be obvious. rEhe movement oli the Luid is facilitated by the downward action ot the plunger at one end ot the tank and the simultaneous upward movement ot the other plunger atV its oppobe seen that one plunger is balanced bythe other, whereas in the single plunger tank construction previously described, the plungers of the individual tanks are purposely mounted. and arranged to themselves operate alternately, as to each other. By this means the same balancing ot' the plungers is provided for and secured. lt will. thus be seen that when machines are built in pairs, either as to the individual tanks, or as to the tanks havino' pairs or' plungers, that the mounting, support-ing, and driving operation ot the plungers contributes very materially to the etliciency and economy oin the operation ot the apparatus as a whole.

is will be seen the arrangementof the gea-ring in the double plunger tanks is somewhat dillierent than that already described, the crank shafts 12a being so arranged and mounted in their bearings 13?' as to provide for the attachment ot the cranks l1a at each end, with the train oit pinion gears 13a, 13, lll in continuous alinement, shaft 1'fiand gears 217e, 18a, 1921, 20 and 2l. transmitting` movement from 'pinion 22a of motor 23a.

The construction and operation of our invention will be readily understood and appreciated by all those familiar with this class ot apparatus, and economical application ot the operating power and greatly contributes to the general eciency ot pickling Vapparatus ot the class i involved.

lWha-t we claim is:

1. Actuating mechanism for a pair of reciprocating plungers comprising a pair of pitmen therefor pivotally connected Vwith each of the plungers at points equi-distant from the center thereof, a pair 'of cranks for each of said pairs of pitmen operating in opposite directions and so timed as to asbe adapted to raise one of said pairs of pitt provides a simple, "direct,

sume the upper and lower vertical positions ,.7

men to their extreme upper vertical position while the other of said pairs of pitmen are moved to their extreme lower vertical position, thereby balancing the consumption of power.

Q. An operating mechanism for a pair of plungers comprising a. pair of pitmen pivotally connected with each plunger at points equi-distant from the center thereof, a pair of cranks for said pitmen operating in opposite directions and so timed as to assume their upper and lower vertical positions simultaneously, a stub shaft for each of said cranks, a common drive shaft geared to said stub shafts, and said pairs of pitmen being so arranged as to raise one of said plungers to its extreme upper vertical position while the other of said plungers is moved to its extreme lower vertical position, thereby effecting a balancing of one plunger by the other, substantially as set forth.

3. An operating mechanism for plungers7 comprising a pair of pitmen pivotally connected with each plunger at each side of the vertical center thereof, a pair of positively revolving cranks for eac-h pair of pitmen7 an operating mechanism therefor so timed and operated as to raise one of said plungers to its eXtreme upper vertical position while the other of said plungers is moved to its extreme lower vertical position, thereby eifecting a balancing of one plunger by the other, substantially as described.

In testimony whereof we hereunto alix our signatures.
